I wrote the play "Borders" many years ago, back in the early 90s, when immigration and border crossings from Mexico were a big issue. There was a news story about a rancher who was killing the illegal border crossers and only got a fine from a Texas judge rather than being arrested for murder.
Immigration is a big issue again so this play continues to have relevance. It's a good one for a current events discussion.

Here is another version called "Hippies, Housewives and Watering Holes" - ironically it seems to make a good comedy, but the 2016 Presidential election is a big of a comedy so that makes sense - http://freedrama.net/hhwh.html
